Solenostemon plant named ‘Balcinsu’

ABSTRACT

A new and distinct cultivar of  Solenostemon  plant named ‘Balcinsu’, characterized by its red brown, green and yellow green-colored foliage and vigorous, upright growth habit.

Latin name of genus and species of plant claimed: Solenostemon scutellarioides.

Variety denomination: ‘Balcinsu’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Solenostemon plant botanically known as Solenostemon scutellarioides and hereinafter referred to by the cultivar name ‘Balcinsu’.

The new cultivar originated in a controlled breeding program in Cartago, Costa Rica during January 2004. The objective of the breeding program was the development of Solenostemon cultivars with unique foliage coloration and leaf shape, upright growth habit, and good sun tolerance.

The new Solenostemon cultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is ‘Elfers’, not patented, characterized by its deep purple, green, and magenta-colored foliage and upright growth habit. The male (pollen) parent of the new cultivar is from a Wizard™ bulk pollen mix, not patented, characterized by its green, red, magenta, yellow-green, and scarlet red foliage colors, zoned and solid foliage color patterns, and upright growth habit. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated cross-pollination during November 2004 in a controlled environment at Cartago, Costa Rica.

Asexual reproduction of the new cultivar by terminal stem cuttings since November 2004 at Cartago, Costa Rica and West Chicago, Ill. has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balcinsu’ as a new and distinct cultivar of Solenostemon plant:

-   -   1. Red brown, green and yellow green-colored foliage; and     -   2. Vigorous, upright growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in foliage color and from plants of the male parent primarily in foliage color and growth habit. Plants of the new cultivar are not as compact as plants of the male parent.

Of the many commercially available Solenostemon cultivars known to the inventor, the most similar in comparison to the new cultivar is ‘Volcano’, not patented. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Volcano’ in the following characteristics:

-   -   1. Plants of the new cultivar have a foliage color different         from plants of ‘Volcano’; and     -   2. Plants of the new cultivar have a more deeply lobed leaf         margin than plants of ‘Volcano’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Balcinsu’. The plants were grown in 4.5 inch pots for 5 weeks in a greenhouse at West Chicago, Ill. Plants were given one pinch at transplant.

FIG. 2 illustrates a close-up view of an individual leaf of ‘Balcinsu’.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2001 edition, except where general color terms of ordinary significance are used. The color values were determined on Apr. 19, 2007 between 1:00 p.m. and 3:00 p.m. under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe plants produced from cuttings from stock plants and grown in a glass-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown at West Chicago, Ill. in 4.5 inch pots for 5 weeks utilizing a soilless growth medium. Plants were given one pinch at transplant. Greenhouse temperatures were maintained at approximately 70° F. to 77° F. (21° C. to 25° C.) during the day and approximately 65° F. to 68° F. (18° C. to 20° C.) during the night. Greenhouse light levels of 2,500 footcandles to 6,000 footcandles were maintained during the day.
